Magic Duel Undress

Inspired by old arcade games Magic Duel Undress is loosely based on My Little Pony's episode "Magic Duel". You take control of Twilight and your objective is to try and push Trixie into a corner by expending your own territory.
Controls are explained in-game (if the keyboard does not respond you might need to click on the game first)
For people with slower computers you can disable the game's grid glow in the right-click menu.
